MrSeb writes: "Intel often uses the Intel Developer Forum (IDF) as a platform to discuss its long-term vision for computing as well as more practical business initiatives. This year, the company has discussed the shrinking energy cost of computation as well as a point when it believes the energy required for “meaningful compute” will approach zero and become ubiquitous by the year 2020. The idea that we could push the energy cost of computing down to nearly immeasurable levels is exciting. It’s the type of innovation that’s needed to drive products like Google Glass or VR headsets like the Oculus Rift. Unfortunately, Intel’s slide neatly sidesteps the greatest problems facing such innovations — the cost of computing already accounts for less than half the total energy expenditure of a smartphone or other handheld device. Yes, meaningful compute might approach zero energy — but touchscreens, displays, radios, speakers, cameras, audio processors, and other parts of the equation are all a long way away from being as advanced as Intel's semiconductor processes."
